WINDOW.

Specification of Letters Patent.

' atented Sept. 2, 1913.

Application filed June 10, 1912. Serial No. 702,781.

1 '0 all whom it may concern Be it known that we, HiRAM A. BANGER and FRANK ,M. BANGER, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Windows, of which the following is a specification.

Our invention relates to improvements in windows, the objectof the invention being to provide an improved construction and arrangement of sash and frame which permits the sash to be swung into the room, and both faces of the glass cleaned while inside the room.

A further object is to provide an improved arrangement of upper and lower sashes, said sashes arranged in pairs-having hinged connection with sliding blocks movable in vertical guides in the center of the window frame, and provide improved means for balancing the sashes, for guiding them in their vertical sliding movement, and for holding them in their normal operative position.

A further object is to provide an improved arrangement of upper and lower sashes arranged in pairs having hinged connection and adapted to be swung inwardly and so arranged that the upper sashes, as well as the lower sashes may be swung into the room.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and ar rangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1, is a View in elevation illustrating our improvements. Fig. 2, is a view in horizontal section on the line 2-2 of Fig. 1. Fig. 3, is a view in horizontal section on the line 3-3 of Fig. 1. Fig. 1, is a view in vertical section on the line 4:4 of Fig. 1. Fig. 5, is a view in vertical section on the line 55 of Fig. 1. Fig. 6, is a fragmentary view in horizontal section on an enlarged scale illustrating the manner of holding the sashes in their guides. Fig. 7, is a fragmentary view in horizontal section through the center guide blocks showing the sashes positioned in such a manner that both guide blocks will be seen. Fig. 8, is a staggered view in ver tical longitudinal section on the line 8-8 of Fig. 4: and Fig. 9, is a view in horizontal section on the line 9 9 of Fig. 8.

Our improved window comprises a boxlike frame 1 having hinged sections 2 to permit access to the weight boxes 3 formed in the side members of the frame, and to the pulley box 1 formed in the upper part of the frame.

Channels 5 are secured to these boxes, and are adapted to support the same in the wall, so that the frame will be securely held and supported upon a suitable sill 6. To the weight boxes 3, parallel vertical channel guides 7 are secured and extend from the sill 6 to the pulley box 4.

Vertical guides 8 are positioned centrally in the frame and are rigidly secured and maintained in parallelism with the channel guides 7 These guides 8 are secured back to back, and while of general channel form, have inturned flanges 9 at their free edges so that the guides S are of clove-tail form in cross section. These guides 8 receive blocks 10 and 11 respectively, the former constituting the guide block for the upper sashes, and the latter the guide block for the lower sashes. To each of these blocks, two sashes are connected. In other words, to the block 10, two upper sashes 12 are connected by hinges 13, and these hinges 13 permit the upper sashes to be swung inwardly, when lowered, and the lower sashes elevated.

The lower sashes 14 are connected by a hinge 15, and the pin 16 of this hinge is projected through perforated cars 17 on guide block 11, so that the sashes may be readily separated from the guide block if desired. The hinges are preferably made integral with the sashes, and as the sashes are preferably of sheet metal, these hinges may be readily formed as integral parts of the sashes when the latter are stamped.

In the central portion of the pulley box l,

two pulleys 18 and 19 are secured, and at 26 are secured on these flexible connectingback the strips 28 against the action of springs 29, so as to release the sash from the frame, and allow it to be swung inwardly on its hinges.

The window opening is of such a length that it permits the lower sashes to be swung I i to their highest positions, andthe upper sashes to their lowest positions, when the latter may be swung into the room under the normal lower sashes.

To form a complete closure when the sashes are in normal position, a plate 32 is secured to the upper pulley box on its outer face, and acts as an apron to overhang the upper edges of the upper sashes when. the latter are in closed position.

It will be noted that with our improvements, the sashes may be readily swung into the room without disconnecting them from their balances. In other words, the guide blocks 10 and 11 are connected with their weights and the sash may be swung into the room and swung back into position without disconnecting the weights.

While, of course, our invention is particularly designed for permitting sashes to be washed inside and outside without the necessity of leaning out of the window, such sashes readily lend themselves to nice adjustment for ventilation, so that the sashes may be swung inwardly as well as moved vertically.

By providing a pair of sashes above and below, the sashes nicely balance each other on the guide blocks, and there is no tendency for lateral binding of the guide blocks, but

said blocks will slide readily in their guides and cannot escape therefrom by reason of I the dovetailed formation above described.

Various slight changes might be made in the general form and arrangement of parts described without departing from our inven tion, and hence we do not limit ourselves to the precise details set forth, but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope ofv the appended claims.

Having thus described our invention, what We claim as new and desire to secure by Letters Patent is:

1. The combination with a window frame, of a vertical guide centrally in the frame, a

, block mounted to slide in said guide, anda pair of sashes connected to said block, sub

stantially as described.

2. The combination with a window frame, of a vertical guide centrally in the frame, a block mounted to slide in said guide, and a pairof sashes hinged to said block, substantially as described.

3. The combination with a window frame, of a vertical guide centrally in the frame, a block mounted to slidein said guide, a pair of sashes connected to said block, and counterbalancing means in the frame connected to said block, substantially as described.

4. The combination with a window frame,

of a vertical guide centrally in the frame, a

block mounted to slide in said guide, a pair of sashes hinged to said block, and counterbalancing means in the frame connected tOi said block, substantially as described.

5. The combination with a window frame,

of a vertical guide located centrally in the frame, a member mounted to move in'the guide, two sashes, and a single hinge pin. connecting both sashes to said movable member, substantially as described. p

6. The combination with a window frame, of a vertical guide located centrally in the frame, a member mounted to move in the guide, two sashes, a single hinge pin connecting both sashes to saidv movable member, said hinge pin extending throughout the length of the sashes and removably held in position,

whereby the sashes may be separated from:

the movable member, substantially as described.
